Abstract

A resin-made gearing apparatus that includes a configuration in which only one tooth flank side of each tooth in one of a pair of gears is provided with an overhang section that is disposed on at least one end portion in a tooth width direction, and overhangs diagonally from the one tooth flank side toward the adjacent tooth side; an end portion in a tooth width direction of each tooth in the other gear is provided with a lightening section that is disposed in a tooth flank of each tooth on an end face on the side of the end portion corresponding to the overhang section of the one gear, so that when the opposite teeth of the pair of gears are meshed with each other, the overhang section of the one gear is elastically deformed and also the lightening section of the other gear is elastically deformed, to absorb a backlash. Thus, the backlash appearing at the meshing of the pair of rein-made gears is absorbed by a backlash absorbing section comprised of the overhang section and the lightening section, and also, the deformation of and stress in the backlash absorbing section are reduced.
